STRENGTHENING-STRIP FOR TRUNKS, 8w.

SPECIFICATION forming part of Letters Patent No. 500,352, dated June 27,1893. Application filed December 2, 1892. Serial No. 458,835. (Nomodel.)

To all whom it may concern..-

Be it known that I, THOMAS N. Roonns, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia, State ofPennsylvania, have invented certain new and useful Improvements inStrengthening- Strips, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements instrengthening strips for use upon trunks and analogous articles, and mynew strengthening strip serves not only to replace the wooden strip butalso as a corner protection to take the brunt of the knocks as the trunkis pitched from place to place.

My improved strip comprises a sheet metal corrugated strip with abacking or filling in the corrugation thereof, the strip having acorrugation at right angles to the main corrugation to serve ata cornernot only to strengthen the trunk atthe corner but to protect the sameupon both sides of the corner.

Other objects and advantages of the inven-' tion will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a vertical cross section througha trunk provided with some of my strengthening strips. Fig. 2 is anenlarged cross section through the strip.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates astrip of metal, preferably sheet metal, shaped in any suitable manner toform a corrugation or convex portion a running longitudinally thereofand which corrugation may be of any desired size relatively to the widthof the metal strip, the corrugation being preferably though notnecessarily in the center of the strip and leaving portions a to lieflat against the body of the trunk and perforated to receive the meanswhich are employed to fasten the same in place.

B is a strip, of any suitable material, preferably wood, fitted to thecorrugation as shown and this may be held therein in any suitablemanner, as by brads, or analogous means I) which need be only ofsufficient length to hold the parts against separation. In order tofurther protect the corner and extension as is provided which may be ofgreater or less length as seen in Fig. 2 and formed between the same andthe corrugation a with an additional corrugation a at right angles tothe corrugation a as seen in Fig. 2, and in this corrugation, which maybe smaller or larger than the corrugation a, as may be deemed best, issecured a backing or filling O, preferably of wood as seen in said Fig.2 and in the forms of strips at the corners in Fig. 1 in which is showna section of a trunk provided with some of my strips.

The strips thus constructed can be placed upon the market in lengths andreadily applied by trunk manufacturers or by anyone else; they may beemployed to replace split and damaged wooden strips upon trunks in use.The metal portion may be formed of steel, iron, brass, gun metal or anydesired material and may be as ornamental as desired. The metal protectsthe backing or filling and prevents breakage thereof, and the backing orfilling prevents disfiguration and breakage of the metal at thecorrugations.

What I claim as new is- 1. A metallic strengthening strip havingcontiguous parallel corrugations at right angles to each other and plainsecuring portions beyond the corrugations at right angles to each otherand in the plane of the base of the adjacent corrugation, substantiallvas specified.

2. A metallic strengthening strip having contiguous parallelcorrugations at right angles to each other and plain securing portionsbeyond the corrugations at right angles to each other and in the planeof the base of the adjacent corrugation, with fillings held in saidcorrugations, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

THOMAS N. ROGERS.
